Using dynamic resources

When you drag cube elements from the Resource View panel to analyze data of a report, sometimes you may find that the cube elements that have been predefined in the business/report cube cannot meet your requirements, in which case, you can create some dynamic resources and use them in the report to get the desired data. Then when you save the report, the dynamic resources will be saved along with the report as its resources.

Dynamic resources are report tab level resources, which means they are only available to the report tab for which they are created.

Dynamic resources in Page Report Studio include formulas and measures.

Creating and using dynamic formulas

You should have some knowledge of the formula syntax before you can successfully compose a formula with no errors. To learn the formula syntax, refer to Formula syntax.

To create a dynamic formula:

1. In the Resource View panel, expand the Dynamic Resources > Formulas node, then click <Add Formula…> to display the Formula Editor window. See the window.

   

2. Enter a name for the formula in Formula Name text field.
3. Compose the formula by selecting the required fields, functions and operators from the Fields, Functions and Operators boxes. You can also write the formula by yourself in the editing box.

   For details about the functions and operators, refer to Built-in functions and Operators.

4. Click the Check button to check whether or not the syntax of your formula is correct.
5. When done, click the OK button to create the formula.

Once a dynamic formula has been created, you can then drag it from the Resource View panel to the desired position in the report as a detail information object for data analyzing. The formulas can also be used to control object properties if you are an advanced user and provided that the Use Dynamic Formula in Property is checked on the Report menu.

Also, if you want to further edit an existing formula or remove any formula that is not required, right-click the formula and then click the corresponding command on the shortcut menu. However, if the formula has been used in the report or referenced by another formula, it cannot be deleted.

Creating and using dynamic measure objects

In Page Report Studio, you can also create dynamic measure objects by mapping them to the available resources which include dimension objects, detail information objects in the current business/report cube and the dynamic formulas that have been created in the report.

To create a dynamic measure object:

1. In the Resource View panel, expand the Dynamic Resources > Measures node, then click <Add Measure…>. The Add Measure dialog is then displayed. See the dialog.

   

2. In the Measure Name text field, specify the display name of the measure.
3. Click the button next to the Mapping Name text field to specify a field or a formula on which the measure object is based.
4. From the Aggregate Function drop-down list, specify the aggregate function for the measure object.
5. When done, click OK to create the measure object.

You can also create a dynamic measure object on a dynamic formula. To do this:

1. In the Resource View panel, right-click the formula in the Dynamic Resources > Formulas node, then select Create Measure from the shortcut menu.
2. In the Add Measure dialog, specify the display name of the measure object and the aggregate function as required.
3. When done, click OK.

Once a dynamic measure object has been created, you can then drag it from the Resource View panel to the desired position in the report so as the get the desired data. And if you want to edit any dynamic measure object or delete it, right-click the measure object and click Edit or Delete on the shortcut menu (a measure object that has been used in report cannot be deleted).
